Killzone 2 native resolution is 640 x 360?

[whatdog]

I found a site claiming that Guerrilla issued technical papers regarding Killzone 2 technology during GDC'09 and is saying that KZ2 native resolution is 640x360 and they're faking the native 720p output by utilizing the CELL processor on doing this work.

Holy fuck, RSX renders Killzone 2 at 640 x 360, then CELL takes it and post process it to fake HD look with post processing??? Unbelievable!!!!

RSX renders at 1/4th of resolution

A whole bunch of blurring added

Combine RSX output with blurring.

to be honest, I haven't read that PDF as I'm not technically versed. I'm interested in reading your opinions regarding this. :smile:

The lower resolution buffers they discussed were regarding particles, transparencies, and post-processing effects, which are different from the game's true 720p render targets. The lower resolution buffers are typical for such effects in order to reduce the hit to memory bandwidth and fillrate. For effects that are by nature blurry and on-screen for very little time, it is a wiser trade-off. In screenshots the lower res buffers will be noticeable to the trained eye to some extent; the game is otherwise rendered at 720p with Quincunx.

Notice: Nothing new or to be worried about, just a misunderstanding of technical information. So locked.
